Smith and wesson revolvers 327 pc

Well ideally I'd get a 4 inch and a 2 inch so I could pick and choose what to run when

I like the idea of having an extra of both
Do you mean like a switch barrel? Or are you planning on buying two guns and just want spare parts?

Either way, unless they've changed, changing the barrel on the scandium Smiths isn't easy. As far as I know, it's a two piece system and requires some special tools to remove. And if you wanted a 4 inch, you'd need the shroud off the 329PD or 325TR and a custom barrel. All said and done, it'd be smarted to just buy more than 1 gun.

I'd like to have a second barrel on hand in case, a 2 inch backup from what I already have would be best for me.
